BT,
One more simple thing you can try.

Type "startup" in search bar Enter
You will get a list of what programs (not individual processes) starting when you start your PC. Make a print screen for your records to revert later. Disable all (or most). Restart and try to see if the glitch is there.

While "pretty" apps installed by manufacturer that "help" your computer might seem convenient, many of them are written poorly and do more harm than good.
